To allwhomz'tmay concern: k 1

Be it known that I, Annxrs L. Laismn, a citizen of the United States, residing at Pittsbur in the county of Crawford and and useful '-Improve'ments in Kerosene Vaporizers; Ii do'hereloy declare the following to be a full, clear, and exact description of the invention, such, as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to Vaporizers, and more f particularly to a kerosene vaporizer for ah'internal combustion engine.

The principal object of the invention is the provision of a device of the above stated character, whereby the kerosene elliciently vaporized so as to produce a highly combustible gas.

Another object of the invention is the provision of a device embodying an intake manifold having an exha st manifold arranged therein, whereby a heat of the exhaust gases from the engine will be sufllis the gasoinitial Withthese and other objmts in view as will appear as the description proceeds, the invention comprises the various noxol features (if construction, combination and arrangementof parts as will. he more fully described ln-ireinaftor and set :l'orth with particularity in the appended. claims,

Fig. girls a detail elevation of a portion of theattaching means, and Fig-"5 a detail e. .evation of the remainm rportlon oi the attachlng means.

.v imilancharacters of reference are used,

to denote like parts throughout the accompanying drawings and the following descrlptlon. Rei'errmg more particularly to the drawings, my improved kerosene vaporizer is shown to consist of a kerosene intake manifold l, which comprises in this instance a horizontally disposed cylindrical manifold pipe 2, which has an angular extension 3 that extends downwardly below the mani fold pipe 2 in angular relation thereto.

Disposed longitudfnally throughthe i11 take manifold 2 is an exhaustmanifold 4 which projects beyond the end 5 of the in 1 take manifold a suitable distance where the end is closed, as clearly indicated by the reference numeral 6. the exhaust manifold extends beyond the opposite end 7 of the intake manifold a suitable distance and i then extends downwardly at an angle to form an extension 8. A suitable pipe, not shown, is connected to this extension 8 and leads to the mulller of the engine. '1 he eXh inst manifold 41, which is horizontally disposed through the intake maniilohl, is providtd with an outlet exhaust pipe extension 9 and, extends down-l wardly through the center of the extension 3 of the intake mam :old. This extension 9 extends through the extension 3 to a point beyond the eniil 10 thereof.

A: lnitterliy valve 11. is arranged in the exttmsion ll liielow the lower end 10 of the The opposite end of, V

intake manifold and. is pniivided with a bell crank arm iii to wltich may be connected a. pull. rod, not shown, whereby the butterfly 'valvo "11 may be opened to allow the ore haunt gases to pass through the extensionto the alnioephero. louneuted t the extcnsion 3 of the intake manifold is a kero sour, intake pipe extension 13, which in this instance, is formed integral with the sec tion 3. Any 'suitahl: or well known form ol. kerosene carburetor, such as conventionally shown and indicated by 14, ay be used and conuected 'zo the iii-take pipe extension 3, and connected to this kerosene carburetor 14. is a supply pipe 15 which loo leads to the earbureter from any suitable source or supply, not shown.

The horizontally disposed portion of the exhaust manifold arranged within the intake manifold 2, and the angularty and downwardly extending extension 9 arranged within the extension 3, are formed with heat radiating pins 10 on the outer and inner surfaces of the manifolds.

While I have shown these heat radiating pins formed and arranged on both the inner and outer surlaees ol the exhaust. manifold pipe., I desire to have it understood that if desired, they may he formed and used on either one 0] the inner or outer surl'ares ot the exhaust manifold pipes. lly the provision of these. heat radiating pins, it will he manifest that as the. exhaust gases pass into the exhaust manifold l and the extension 5 thereof that these pills will become ver v hot, and as a result, radiate a greatdeal more heatwit-hin and around the exhaust manifolds to more ellieiently vaporize the kerosene in the intake manifold around the extension 5).

The horizontaltv disposed intake nmnil'old. 2 is termed with nipples lli' that are tlt' signed to seat within the intake openings 1? ol" the engine ovlinders lH. 'lhese nipples are providiul with outlet openings li through which vaporized gases pass or enter the engine.

'l'he. exhaust n'ianil'old pipe. l is l'ormed with nipples or extensions :20 that extend through the intake. manil'old 2 and ron|- lnunieate with the interior of the exhaust llltlllltOltl l. lhese nipples i are also seated in the exhaust openings it of the engine. cylim'lers .l'S. Additional nipples 2'!" are termed integral with the exhaust manil'old t at points beyond and adjarent the opposite ends of the intake manil'ohl i. and likeise have their outer ends seated within the exhaust openings :21 of the engine eylimlers.

.ln order to attaeh my impr ved lo-rosene. vaporizer to the engine cylinders. I employ in this inslaxae,.T bolts 23 that have the outer ends ol the stems 2t threadtut and passed through hores 'tiormed hetween the cylinders of the'engine and are secured therein try the nuts 25 threadedly ronne -terl to their ends. Each of the T-holts 23 is formed with a head 2t} having perforations 37 at its opposite end and through whirl-1 are. de signed to pass the threaded ends o'l U- holts 28, which latter are secured. in plaire hy nuts 29 threadedlyconnected to the ends of the U-bolts.

\Vhile I have shown two of these 'fastening or securing means, in Fig. l of the drawings, it is to be understood that any desired numher.,oli' these securing means may be employed to rigidlfand lirmly hold the vaporizer in position. i

Tapped into or t-hreadedly connected with the intake manifold extension 3 is a valve gasolene pipe 32. By the use of this valve an initial supply of gasolene may be allowed to enter the intake manifold to give the engine an initial start. In starting the engine, gasolene is admitted through this valve 30 on which to run the motor until the exhaust pipe has become suflieiently heated by the passage of the burnt gases therethrough, to thoroughly vaporize the kerosene that is being sucked into the intake. manifold l'roni the ea rhureter l-t. \Vhen the exhaust pipes have become sulliciently heated to thoroughly vaporize the kerosene, the valve 30 elosed, whence it will be seen that; the engine. will run entirely upon the kerosene vapor or gas.

A valve 33 is tapped into or thradedly onneeted to the intake manifold 2 and is provided with a valve stem 34 that extends upwardly to the dash of the automobile within easv rearh of the operator. A water pipe 35 is connected to this valve which leads to the valve from any suitable source of supply. .ly the provision of this valve 33, itwill he apparent that a stream of water of any desired size may be introduced into the intake manil'old of the vaporizer, where it will be instantly converted into steam [or eommingling with the vaporized.

kerosene and hot air. This stam. Will not only help to more thoroughly vaporize the kerosene within the intake manifold but will to a great extent assist in the removal of any carbon that may be within the engine cylinder and also prevent the rapid accumu- .latlon of carbon in the cylinders.

in the operation of the device and in the initial, starting of the engine the "alve 30 is opened 'whieh will permit of the desired amount of gasolene entering the intake manifold with which to run the engine until the. engine has been run sulliciently to cause the burnt exhaust gases to heat the exhaust n'ianitold to such a degree of temperature as to readily and qniekly vaporize the kerosene surroumling it that is being sucked in from the carlnireter, after which the valve 30 is closed, thus cutting off the supplvof gasolene and permitting the motor to run entirely upon the kerosene vapor or gas that is being sucked in from the carburetor.

By the construction shown and described it will be apparent that my improved term of kerosene vaporizer will be equally as effective in operation, when the motor is traveling up a hill as it; will when it is traveling on a level For if it desired to climb a hill the huttertly valve '11 may he opened so as to allow the exhaust gases to exhanstdirectly to the atmos 'ihere without having to pass through the mufller of the machine, the exhaust gases in passing through the outlet extension 9 heating the pins 16 so that they will radiate their heat in all directions around the interior of the intake manifold suflicientl to va orize the kerosene that is being suc ed in rom the intake pipe 13 to the intake manifold section or extension 3. Thus it will be seen that a complete and eflicient vaporization of the kerosene may be thereof, an exhaust pipe extension. disposed through and in spaced relation to the walls of the depending section of the intake mani fold, and a valve arranged in the lower end of. said exhaust pipe extension adapted to i control the heat adiating efficiency of the exhaust manifolu within the intake mani- "fold.

2. An engine manifold comprising an intake manifold having outlet openings there in, an extension pipe projecting from said intake manifold, a hydro-carbon supply pipe connected to said extension, an exhaust manifold disposed through and in spaced relation to tie Walls of the intake manifold inlet, arms projecting laterally from the exhaustmanifold through said intake manifold, and exhaust pipe extension extending through and in spaced relation to the walls of the intake extension, and heat radiatin means carried. by said exhaust manifold and exhaust extension pipe.

3. An engi 1e manifold comprising an intake manifold, consisting of a horizontally disposed manifold, and an extension pipe extending downwardly from said horizontal manifold, a hydrocarbon intake pipe con nected to the lower end of said depending extension, said intake manifold being pro vided with on ,let openings, an exhaust manifold. disposed through and in spaced relation 5 to the Walls (f the intake manifold, an exhaust pipe tension disposed through and in spaced relation to the Walls of the cl epending section cf the intake manifold, heat radiating pins disposed on the inner and outer surfaces of the exhaust manifold and the exhaust dapending section, and a valve arranged in the lower end of said exhaust pipe depending section, adapted to be actuated to control the heat radiating efficiency of said exhaus; manifold, exhaust depending section, and head radiating pins carried thereby.

In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.
